420664049 Camshaft Position Sensor for Sea-Doo GTX 155 STD 1503 2014

Camshaft Position Sensor for Sea-Doo

This camshaft position sensor for Sea-Doo, OEM cross-reference 420664049, measures camshaft rotation and delivers timing data to the engine control module so ignition and fuel delivery stay synchronized.

Overview

This camshaft position sensor for Sea-Doo is a direct-fit replacement built for 1503 engine platforms. When the original sensor fails, the ECU loses its camshaft reference, which can trigger fault codes, rough running, or a no-start condition. Fitting this camshaft position sensor for Sea-Doo restores accurate timing signals so the engine performs as intended.

Fits These Machines

• for Sea-Doo GTX 155 STD 1503, 2014

On-The-Job Use

• Replacing a failed or intermittent original camshaft sensor during engine service
• Diagnosing camshaft timing or synchronization fault codes
• Top-end rebuilds where the sensor is replaced as preventive maintenance
• Restoring consistent cold and hot starting on 1503-powered watercraft

Specs At A Glance

Good To Know

Q: What symptoms point to a bad camshaft position sensor? A: Watch for camshaft timing fault codes, hard starting, rough idle, or an engine that cranks without firing. A scan tool confirming signal loss helps verify the sensor before replacement.

Q: Will the engine relearn camshaft timing after installation? A: On most 1503 platforms, synchronization is relearned automatically on the first start. Clearing stored fault codes afterward confirms the repair is complete.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
